Abstract
The utility model relates to a die, in particular to a backrinding resistant rubber die. The rubber die comprises an upper die, a middle die and a lower die, and is characterized in that the parting surfaces among the upper die, the middle die and the lower die are arranged at certain height where the product plane extends to keep away from the product plane. The die structure adopts a die with a closed opening. The backrinding resistant rubber die solves the problems that the traditional die is parted at the same plane of a product, the pressure in product die cavity and the product compaction degree are insufficient, and the product inconsistency after die pressure relief is large; and backrinding can occur in the positions of the parting surfaces after the product is demoulded, therefore the appearance and the size of the product are affected. The rubber die has the advantages of easy packing of die-pressed products, sizing material saving, consistent product size, fine appearance, great reduction of rejection rate and manufacturing cost saving, thereby capable of meeting actual needs.
Description
Technical field
The utility model relates to a kind of mould, especially a kind of rubber mold of anti-back flow.
Background technology
The product problem of opening all around all can appear in a lot of thick rubbers at present, it is back flow, because conventional mould structure all is the same plane punishment type at product, this mould structure design belongs to the opening mould, its shortcoming is that the product type cavity segment can exist insufficient pressure, the problem that the product packing is not enough, and the fluctuation of product can be very big after the mould release like this, and will produce the phenomenon of back flow at the somatotype place behind the product stripping, thereby influence the outward appearance and the size of product.Need a kind of rubber mold of anti-back flow of the plane somatotype of avoiding product, the situation of back flow can not appear in the product that makes mold pressing go out, and satisfies the needs of actual conditions with this for this reason.
The utility model content
The rubber mold of a kind of anti-back flow of the present utility model, it has solved the same plane punishment type of conventional mould at product, there is insufficient pressure in the product type cavity segment, the product packing is not enough, the fluctuation of product is big after the mould release, and can produce back flow at the die joint place behind the product stripping, thereby influence the outward appearance of product and the problem of size, also have the easy filler of its molded product, save rubber material using quantity, product size is stable, exquisite appearance, percent defective reduces greatly, and production cost saving can satisfy the needs of actual conditions.
The technical scheme that the utility model adopted is:
A kind of rubber mold of anti-back flow comprises patrix, middle mould and counterdie, it is characterized in that: the die joint of patrix and counterdie and middle mould is arranged on product plane and extends the certain height place, avoids the plane of product.
The rubber mold of described anti-back flow, its mould structure belongs to the mould of remaining silent.
Like this when work, the rubber mold of a kind of anti-back flow of the present utility model, it will have the opening mode structure now and improve, thereby avoid causing its die joint place to be easy to generate the problem of back flow at the plane of product somatotype, but after certain altitude is extended on the plane of product somatotype again, product is with regard to problem that can not the build-up of pressure deficiency like this, and overlap can directly not influence product size and pressure yet.This mould structure belongs to the mode structure of remaining silent, all pressure all concentrate on mold cavity and partly bear, after filling the filled with product die cavity, sizing material just can form overlap, not only density is good for the product that comes out of mold pressing like this, and product can not fluctuate, make product size keep stable, thereby solved the problem of back flow.
The rubber mold of a kind of anti-back flow of the present utility model, it has solved the same plane punishment type of conventional mould at product, there is insufficient pressure in the product type cavity segment, the product packing is not enough, the fluctuation of product is big after the mould release, and can produce back flow at the die joint place behind the product stripping, thereby influence the outward appearance of product and the problem of size, also have the easy filler of its molded product, save rubber material using quantity, product size is stable, exquisite appearance, percent defective reduces greatly, and production cost saving can satisfy the needs of actual conditions.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is original opening mode structure mould structure schematic diagram;
Fig. 2 is its product back flow schematic diagram of original opening mode structure mould;
Fig. 3 is the rubber mold structural representation of a kind of anti-back flow of the utility model.
Among the figure, 1 is patrix, and 2 is middle mould, and 3 is counterdie, and 4 is die joint, and 5 is product.
The specific embodiment
Embodiment
As shown in Figure 1 to Figure 3, a kind of rubber mold of anti-back flow comprises patrix 1, middle mould 2 and counterdie 3, and patrix 1 and counterdie 3 are arranged on product 5 planes extension certain altitude with the die joint 4 of middle mould 2, avoid the plane of product 5.This mould structure belongs to the mould of remaining silent.
Like this when work, the rubber mold of a kind of anti-back flow of the present utility model, it will have the opening mode structure now and improve, thereby avoid causing its die joint place to be easy to generate the problem of back flow at the plane of product somatotype, but after certain altitude is extended on the plane of product somatotype again, product is with regard to problem that can not the build-up of pressure deficiency like this, and overlap can directly not influence product size and pressure yet.This mould structure belongs to the mode structure of remaining silent, all pressure all concentrate on mold cavity and partly bear, after filling the filled with product die cavity, sizing material just can form overlap, not only density is good for the product that comes out of mold pressing like this, and product can not fluctuate, make product size keep stable, thereby solved the problem of back flow.
The rubber mold of a kind of anti-back flow of the present utility model, it has solved the same plane punishment type of conventional mould at product, there is insufficient pressure in the product type cavity segment, the product packing is not enough, the fluctuation of product is big after the mould release, and can produce back flow at the die joint place behind the product stripping, thereby influence the outward appearance of product and the problem of size, also have the easy filler of its molded product, save rubber material using quantity, product size is stable, exquisite appearance, percent defective reduces greatly, and production cost saving can satisfy the needs of actual conditions.
Obviously, the foregoing description of the present utility model only is for the utility model example clearly is described, and is not to be qualification to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here can't give exhaustive to all embodiments.Everyly belong to the row that conspicuous variation that the technical solution of the utility model extends out or change still are in protection domain of the present utility model.
Claims (1)
1. the rubber mold of an anti-back flow comprises patrix, middle mould and counterdie, it is characterized in that the die joint of patrix and counterdie and middle mould is arranged on product plane extension certain height place, avoids the plane of product.
